Determination of the characteristic directions of lossless linear optical elements
Hanno Hammer
We show that the problem of finding the primary and secondary characteristic directions of a linear lossless optical element can be reformulated in terms of an eigenvalue problem r…

Collective states in highly symmetric atomic configurations, and single-photon traps
Hanno Hammer
Abbreviated Abstract: We study correlated states in a circular and linear-chain configuration of identical two-level atoms containing the energy of a single quasi-resonant photon i…

Collective excitations in circular atomic configurations, and single-photon traps
Hanno Hammer
Correlated excitations in a plane circular configuration of identical atoms with parallel dipole moments are investigated. The collective energy eigenstates, their level shifts and…
